Dear PACE users,
Quarterly maintenance is fast approaching. Starting at 6:00am on Thursday, October 13, all resources managed by PACE will be taken offline. Maintenance will continue through Saturday evening unless we are able to finish sooner.
Our major activity this maintenance period will be an operating system upgrade for all compute nodes, head nodes and interactive nodes. This update will take us from RedHat 6.5 to RedHat 6.7, and includes important security and bug fix updates to the operating system, a new Infiniband layer and some recompiled versions of existing /usr/local software. Some applications have shown increased performance as well.
*** IMPORTANT USER ACTION NEEDED ***
PACE staff have been testing this upgrade using various existing applications but we need your help to ensure a smooth rollout. As of today, we have begun applying these updates to our TestFlight cluster, which is available for all to use. We’ll send out a follow up communication when it is ready. PLEASE, PLEASE, PLEASE, use the next few weeks to try your codes on the TestFlight cluster and send feedback to pace-support@oit.gatech.edu. We would especially like to hear of any issues you may have, but reports of working applications would be helpful as well.
Our goal is to provide the best possible conversion to the updated operating system, and ask that you please take the opportunity to help us ensure a smooth transition back into normal operation by availing yourself of the TestFlight cluster.
